Rugby is a contact sport associated with a large number of injuries. According to our survey with questionnaire for 108 college, 190 high school, 68 junior high, and 15 female rugby players, more than 50% of the injuries are sustained traumatic injuries to the lower extremities mostly ankle and knee joints. Balance board training has been shown to reduce the incidence of ankle sprains in different sports. The purpose of this study was to investigate the effects of balance board training on strength gain of lower extremities and postural sway. Balance board training for 10-15 minutes was per-formed every day for 2 months. Before and after the training, muscle strength of knee flexor, extensor, ankle dorsiflexor, planter flexor, inverter, evertor and postural sway of the lower extremities were measured in the players. Postural sway was recorded using the gravicorder(anima, GS-11); maximum isometric strength was measured using hand held dynamometer (Power Track II ) for each leg separately. The results showed no significant improvement in postural sway. The strength of knee flexion, ankle dorsiflexion, and ankle planter flexion increased on the right and left leg (P < 0.01). The significant increase of knee extension showed only on the right leg (P < 0.05). After balance board training, the initial difference between right and left leg decreased in knee flexion, ankle dor-siflexion, inversion, and eversion. These results indicate balance board training to be effective for the gain in muscular strength.
